access and algorithmic products and the Millennium Alternative Trading

Euronext. “This transaction complements our strategic corporate goals
and expands our points of connectivity with customer trading
communities. We would also like to recognize the efforts of NYFIX

of origin in the trade flow process,” said Stanley Young, Chief
Executive Officer of NYSE Technologies and co-CIO, NYSE Euronext. “This
includes more than 450 buy-side institutions and more than 600 sell-side
institutions, and connections to exchanges and other electronic trade
execution venues around the world.”
